* Switch time_state to explicit default initialization instead of value ↵20220623.1Gravatar Andy Getz2022-08-31
| | | | | | | | | | | | initialization. (#1261) It looks to me like the language rules treat these the same for this type, but evidently GCC feels differently. This only matters under TSAN where SpinLock has a non-trivial destructor, and under C++20 where ABSL_CONST_INIT is implemented (as constinit) by gcc.

* Optimize SwissMap iteration by another 5-10% for ARMGravatar Abseil Team2022-06-09
| | | | | | | | | | | | | | | | | | | https://pastebin.com/fDvgWgHe After having a chat with Dougall Johnson (https://twitter.com/dougallj/status/1534213050944802816), we realized that __clzll works with zero arguments per documentation: https://developer.arm.com/documentation/101028/0009/Data-processing-intrinsics ``` Returns the number of leading zero bits in x. When x is zero it returns the argument width, i.e. 32 or 64. ``` Codegen improves https://godbolt.org/z/ebadf717Y Thus we can use a little bit different construction not involving CLS but using more understandable CLZ and removing some operations.

* absl: correct the stack trace path on RISCVGravatar Saleem Abdulrasool2022-06-08
| | | | | | | | | | | | | | | | | | | When we would perform a stacktrace using the frame pointer walking, because we did the adjustment for the return address separately, we were misaligning the stack size and frame. Simplify the logic and correct the offset. The recovered frame pointer provides us with the return address of the current frame and the previous frame's frame pointer. Subsequently, we decide if we want to record this frame or not. The value in `next_frame_pointer` already points to the value from the previous stack frame (that is the next frame pointer to iterate). As such, the value computed by `ComputeStackFrameSize` is the value for the current frame. This was offset by one previously. Take the opportunity to clean up some of the local comments, fixing typos and splitting up the comments to reflect the lines that they are associated with.

* Ignore invalid TZ settings in testsGravatar Benjamin Barenblat2022-06-06
| | | | | | | | | | | | | For portability, absl_time_test builds a small, incomplete tzdata database into the test binary and uses that instead of the system tzdata database. (absl_time_test needs to run on some platforms that lack a system tzdata database.) However, this causes issues if TZ is set to something that isn’t in the test database. To address them, fall back to America/Los_Angeles if TZ is set to an unknown value during testing.

* Optimize SwissMap for ARM by 3-8% for all operationsGravatar Abseil Team2022-06-06

Even though 16 byte NEON achieves higher throughput, in SwissMap it's very important to catch these Matches with low latency as probing on average happens at most once.
